Method for Preparing Water-Soluble Tobacco Flavor in Gel State

ABSTRACT

A method for preparing water-soluble tobacco flavor in gel state is disclosed. The method includes the following steps: mixing food thickener with glycerol in a mass ratio of 1:50 to 1:5 and mixing to uniform, heating to a temperature of 80° C. to 100 ° C. and keep stirring till dissolve thoroughly, homogenizing for 5 to 15 minutes, cooling to a temperature of 30° C. to 50° C., adding water-soluble tobacco flavor and mixing to uniform, and placing at least 12 hours at a temperature of 1° C. to 30 ° C. to obtain a final product. The product obtained by the method can greatly inhibit volatilization of the tobacco flavor, maintain fragrance completely, reduce the loss caused by volatile components, and can be easily transported and stored.

FIELD OF THE INVENTION

The present invention relates to the field of tobacco flavor, and moreparticularly to a method for making water-soluble tobacco flavor intogel state.

BACKGROUND OF THE INVENTION

Fragrance type and fragrance style of tobacco flavor determines, in asense, the quality and taste of cigarette. Usually in the cigaretteburning process, some organics with spicy taste will be generated. Ifsome flavor is added into the cigarette, the spicy taste produced in thecigarette burning process will be concealed. Currently used tobaccoflavor is mostly a direct extract in form of liquid, extractum oressential oil, which easily leads to the volatilization loss offragrance.

In the cigarette manufacturing process, in order to improve thefragrance of cigarette, it's necessary to add tobacco flavor intocigarette raw materials artificially. A current method for adding flavoris to spray tobacco flavoring essence, which is dissolved in somesolvents such as water, ethanol, glycerol, propylene glycol, etc., ontothe cigarette raw materials. The disadvantage of such method is thatsome tobacco flavor with bad solubility cannot be uniformly dissolved inthe solvent; therefore the tobacco flavor cannot be sprayed and added tothe cigarette raw materials uniformly. Furthermore, since the tobaccoflavor is liquid, the loss or change of fragrance is easily to be causedby volatilization. Atomized liquid for electronic cigarette is usually aliquid, so it is also easy to cause volatilization loss of fragrance. Incurrent related technologies, there is few report on preparing tobaccoflavor into gel state.

SUMMARY OF THE INVENTION

Based on the above, it is an object of the present invention to overcomethe drawbacks of the prior technologies by providing a method for makingwater-soluble tobacco flavor into gel state, which can significantlyimprove fragrance retention of the tobacco flavor, and greatly reducevolatilization loss.

According to one aspect of the invention, a method for preparing awater-soluble tobacco flavor in gel state includes: mixing foodthickener with glycerol in a mass ratio of 1:50 to 1:5, mixing touniform, heating to a temperature of 80° C. to 100° C. and keep stirringtill dissolve thoroughly, homogenizing for 5 to 15 minutes, cooling to atemperature of 30° C. to 50° C., then adding water-soluble tobaccoflavor, mixing to uniform, and placing at least 12 hours at atemperature of Ito 30° C. to obtain final product.

Preferably, the food thickener is sodium polyacrylate.

The significant advantages of preparing water-soluble tobacco flavorinto gel state are as follows:

(1) The water-soluble tobacco flavor is prepared into gel state in thepresent invention, which makes its use be easier and its package,shipping and store be more flexible.

(2) The water-soluble tobacco flavor is prepared into gel state in thepresent invention, which greatly improves the heat resistance, lightresistance and oxygen resistance abilities of the tobacco flavor, andtherefore avoids discoloration and fragrance change caused by outsideinfluences like direct light, heat, etc.

(3) The water-soluble tobacco flavor is prepared into gel state in thepresent invention, which greatly inhibits the volatilization of thetobacco flavor, completely preserves the fragrance, and reduces the losscaused by some volatile components.

(4) The water-soluble tobacco flavor is prepared into gel state in thepresent invention, which improves the quality of the product, andincreases the fragrance retention.

(5) The water-soluble tobacco flavor is prepared into gel state in thepresent invention, therefore the prepared product does not includewater, and can be kept at a low temperature of −20° C. without freezing.

(6) The present invention can be carried out with low cost, can easilyobtain raw materials and relatively simple production process which isconvenient to be actually implemented.

In addition, sodium polyacrylate can be dissolved in glycerol to form avery viscous and transparent liquid, of which the viscosity is due toionic phenomenons of many anionic groups making molecular chainincrease, and making apparent viscosity increase, so as to produce ahigh viscous solution, which, when stored for a long time, has aviscosity minimally changing over time.
